What is the legal Blood Alcohol Concentration (BAC) limit for commercial drivers?

The legal Blood Alcohol Concentration (BAC) limit for commercial drivers is set at 0.04%. This standard is established to ensure higher safety standards for individuals operating large and potentially dangerous vehicles, as commercial drivers have a greater responsibility on the road compared to non-commercial drivers. A BAC of 0.04% is significantly lower than the standard 0.08% limit for non-commercial vehicle operators.

This lower threshold recognizes the increased risks associated with driving larger vehicles, which can have more severe consequences in the event of an accident due to their weight and size. By enforcing a stricter BAC limit for commercial drivers, regulatory authorities aim to enhance road safety and reduce the likelihood of accidents related to impaired driving. This is particularly crucial because commercial drivers are often responsible for transporting goods, passengers, and equipment, where any impairment can lead to disastrous outcomes.
